Hello Dawn,
Before you start looking for volunteer experience, my first question would be what jobs have you applied for?
Most people want hospital experience, as they know they'll learn the most in an acute care facility.
Right now, with fewer patients and filled beds, hospitals are shying away from new graduates because of the long orientations they need.
You can find work in nursing homes, doctors offices, clinics, all of which would count more when a hospital job became available than volunteer experience (and it would provide a paycheck as well).
Volunteer options would involve the Peace Corps, etc. You can find several organizations listed here:

Hope that is helpful.
